Just had a thought, the regen is so good on the I Pace (when set to max) that the car slows down really quickly, when driving a demo car for a few hours at the weekend, I hardly had to use the brakes at all, so I wondered, when the car is slowing down using the regen only, do the brake lights come on to show drivers behind you that your are slowing down? not having had an EV before, the thought just crossed my mind when driving my own car today.
